Description

Pneumatisch oder elektromotorisch betätigbare Scheibenbremse Pneumatically or electromotively operated disc brake
Die vorliegende Erfindung betrifft eine pneumatisch oder elektromotorisch betätigba- re Scheibenbremse, mit einem eine Bremsscheibe übergreifenden Bremssattel, mindestens einer Zuspanneinrichtung zum Zuspannen der Scheibenbremse mittels eines verschiebbar geführten Elements, insbesondere einer Traverse, wobei das verschiebbar geführte Element mindestens eine Gewindebohrung aufweist, in die eine Stellspindel eingeschraubt ist, die ein Druckstück trägt, mit welchem ein Bremsbelag gegen die Bremsscheibe drückbar ist, einer mit der Stellspindel in Wirkverbindung stehenden Nachstelleinrichtung zur Nachstellung des Lüftspiels, und einem bis zu einem bestimmten Drehmoment verdrehhindernd auf die Stellspindel wirkenden Sicherungselement.The present invention relates to a pneumatically or electromotively actuated disk brake, with a brake caliper spanning a brake disk, at least one application device for applying the disk brake by means of a displaceably guided element, in particular a cross member, the displaceably guided element having at least one threaded hole into which one Adjusting spindle is screwed in, which carries a pressure piece with which a brake pad can be pressed against the brake disc, an adjusting device which is operatively connected to the adjusting spindle for adjusting the air gap, and a securing element which prevents rotation of the adjusting spindle up to a certain torque.
Bei einer derartigen Schreibenbremse, wie sie beispielsweise aus der DE 94 22 342 Ul bekannt ist, wirkt ein Drehhebel auf eine Traverse ein, in der vorzugsweise zwei Stellspindeln gelagert sind, die jeweils ein Druckstück zur Aufnahme eines Bremsbelages aufweisen, das bei Bremsungen an eine Bremsscheibe angedrückt wird. Die beiden Stellspindeln sind mit einem Außengewinde versehen und jeweils in eine Gewindebohrung der Traverse eingeschraubt.In such a writing brake, as is known, for example, from DE 94 22 342 Ul, a rotary lever acts on a crossmember, in which preferably two adjusting spindles are mounted, each of which has a thrust piece for receiving a brake pad, which is applied to a brake disc when braking is pressed. The two adjusting spindles are provided with an external thread and each screwed into a threaded hole in the traverse.
Mittels einer Nachstelleinrichtung, die einer der Stellspindeln zugeordnet ist, und einem Mitnehmer der anderen Stellspindel wird durch Verdrehen der Stellspindeln in den Gewindebohrungen bei Verschleiß des Bremsbelages die Bremsbacke so weit zugestellt, dass ein Lüftspiel zwischen dem Bremsbelag und der Bremsscheibe im wesentlichen immer konstant bleibt. Um zu verhindern, dass durch Erschütterungen während des Fahrbetriebs die Stellspindeln ungewollt ihre Lage - und somit den Abstand zwischen dem Bremsbelag und der Scheibenbremse, also das Lüftspiel - verändern, werden Sicherungselemente eingesetzt, die drehhemmend auf die Stellspindeln einwirken, so dass die genannte unbeabsichtigte Verstellung verhindert wird. Dabei liegen die Sicherungselemente reibend an der Stellspindel oder Teilen davon an. Die Reibkraft ist so bemessen, dass bei einem durch die Nachstelleinrichtung aufzubringenden bestimmten Drehmoment die Drehung der Stellspindeln problemlos möglich ist, wobei dieses Drehmoment größer ist als ein solches, wie es sich aus den Erschütterungskräften im Fahrbetrieb ergeben kann.By means of an adjusting device, which is assigned to one of the adjusting spindles, and a driver of the other adjusting spindle, the brake shoe is adjusted by turning the adjusting spindles in the threaded bores when the brake lining wears down, so that an air gap between the brake lining and the brake disk remains essentially constant. In order to prevent the adjusting spindles from inadvertently changing their position due to vibrations while driving - and thus the distance between the brake pad and the disc brake, i.e. the air gap -, safety elements are used that have an anti-rotation effect on the adjusting spindles, so that the aforementioned unintentional adjustment is prevented. The locking elements rub against the adjusting spindle or parts thereof. The frictional force is dimensioned such that, given a specific torque to be applied by the adjusting device, the adjustment spindles can be rotated without problems, this torque being greater than that which can result from the vibration forces during driving.
Ähnliche Probleme treten bei rein statischem Takten durch ein Taumeln des Nachstellerantriebs gegenüber den Nachstellgliedern (Gewinderohren bzw., Stellspindeln auf), speziell, wenn es zu einem Mittenversatz kommt, wodurch ein Drehimpuls aus- geübt wird, dem eine Bremswirkung am Gewinderohr entgegenstehen muss.Similar problems occur with purely static clocking due to wobbling of the adjuster drive in relation to the adjusters (threaded pipes or adjusting spindles), especially if there is a center offset, which exerts an angular momentum which must be countered by a braking effect on the threaded pipe.
Um diesen Effekten entgegen zu wirken, müssen die Gewinderohre daher mit einem recht genau einstellbaren und auch über der Zeit und der Belastung weitestgehend konstant einstellbaren Reibmoment versehen sein. Genau dies ist beim Stand der Technik nur eingeschränkt möglich.In order to counteract these effects, the threaded pipes must therefore be provided with a friction torque that can be set quite precisely and that can also be largely set over time and the load. Exactly this is only possible to a limited extent in the prior art.
So besteht ein bekanntes Sicherungselement aus einer (Sekundär-)Dichtung, die in einem dem Druckstück zugewandten Endbereich der Stellspindel angeordnet ist und sichernd in die Stellspindeln eingreift.Thus, a known securing element consists of a (secondary) seal which is arranged in an end region of the adjusting spindle facing the pressure piece and which engages securely in the adjusting spindles.
Unter anderem zur Funktion der Drehhemmung besteht die Sekundärdichtung bzw. das in die Stellspindel greifende Teil aus einem Elastomer wie Silikonkautschuk, das in die Sekundärdichtung integriert ist.Among other things regarding the function of the anti-rotation device, the secondary seal or the part reaching into the adjusting spindle consists of an elastomer such as silicone rubber, which is integrated in the secondary seal.
Insbesondere bei schwerem Einsatz erreichen die Stellspindeln Temperaturen, denen das aus Kunststoff bestehende Sicherangselement dauerhaft nicht standhalten kann. Auch eine Versprödung und Alterung des Materials sowie Reaktionen auf eine unvermeidliche Fetteinwirkung begrenzen die Lebensdauer, so dass ein verschleißbedingtes Auswechseln in wirtschaftlich wenig sinnvollen Intervallen notwendig wird.Especially in heavy use, the adjusting spindles reach temperatures that the safety element made of plastic cannot withstand in the long term. Embrittlement and aging of the material, as well as reactions to the inevitable effects of grease, also limit the service life, so that wear-related replacement at economically unreasonable intervals is necessary.
Zwar sind Lösungen bekannt, bei denen in die Traverse eingesetzte metallische Ringe oder Zungen in Eingriff mit den Stellspindeln kommen, jedoch ist diese Konstruktion i.allg. nur unter einer besonderen mechanischen Bearbeitung der Traverse realisierbar, was naturgemäß eine Erhöhung der Fertigungskosten zur Folge hat.Although solutions are known in which metallic rings or tongues inserted into the crossbeam come into engagement with the adjusting spindles, this construction is generally. can only be realized with special mechanical processing of the crossbeam, which naturally leads to an increase in production costs.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Scheibenbremse der gattungsgemäßen Art so weiter zu entwickeln, dass mit konstruktiv einfachen Mitteln eine hohe Standzeit der eingesetzten Sicherungselemente erreicht wird, wobei auch eine möglichst präzise und über die Betriebszeit konstante Festlegung des Grenzdrehmomentes, bis zu welchem die Sicherungselemente ungewollte Drehungen des Stellspindeln verhindern, realisierbar sein soll.The present invention is therefore based on the object of further developing a disc brake of the generic type in such a way that a long service life of the securing elements used is achieved with structurally simple means, and the limit torque, up to which, is as precise as possible and constant over the operating time the locking elements prevent unwanted rotations of the adjusting spindles, should be realizable.
Diese Aufgabe wird durch eine Scheibenbremse mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a disc brake with the features of claim 1.
Danach ist das Sicherungselement als Federring mit wenigstens einem oder mehreren von über den Umfang verteilten Federbügeln ausgebildet, die außerhalb des Innengewindes des verschiebbar geführten Elements - insbesondere der Traverse - reibend an der Stellspindel anliegen.Thereafter, the securing element is designed as a spring ring with at least one or more spring clips distributed over the circumference, which frictionally rest on the adjusting spindle outside the internal thread of the displaceably guided element - in particular the cross member.
Ein besonderer Vorteil besteht in der genauen Bestimmbarkeit des zudem dauerhaft sehr konstanten Grenzdrehmomentes, bis zu welchem Drehungen der Stellpindel(n) verhindert werden.A particular advantage is the precise determination of the limit torque, which is also very constant over the long term, up to which rotations of the adjusting spindle (s) are prevented.
Durch die gewählte konstruktive Ausbildung ergeben sich ferner eine ganze Reihe von Vorteilen sowohl hinsichtlich des Betriebs der Scheibenbremse wie auch hinsichtlich der Herstellung der Sicherungselemente und hinsichtlich deren Montage. Insbesondere ist auch die leichte Nachrüstbarkeit bei bestehenden Scheibenbremsen zu nennen.The chosen design also results in a whole series of advantages both with regard to the operation of the disc brake and with regard to the manufacture of the securing elements and with regard to their assembly. The easy retrofitting of existing disc brakes should also be mentioned in particular.
Zur Bestimmung des Grenzdrehmomentes, bis zu welchem Drehungen der Stellpin- del(n) verhindert werden, bietet es sich insbesondere an, die Art und die Anzahl der Federbügel zu variieren. Bevorzugt ist wenigstens ein Federbügel vorgesehen. Noch vorteilhafter ist aber eine Anordnung mit drei oder mehr, insbesondere fünf oder sechs Federbügeln, da diese einerseits noch gut am Ringelement angeordnet sein können und andererseits von mehreren Stellen her eine gleichmäßige Krafteinwir- kung auf die Stellpindel(n) sichern.To determine the limit torque up to which rotations the adjusting spindle (s) are prevented, it is particularly advisable to vary the type and number of spring clips. At least one spring clip is preferably provided. However, an arrangement with three or more, in particular five or six spring clips is even more advantageous, since on the one hand these can still be arranged well on the ring element and on the other hand ensure a uniform force effect on the adjusting spindle (s) from several points.
Neben der hinsichtlich ihrer Dimensionierung wählbaren Reibfläche ist auch durch die Bestimmung der Federkraft die Drehhemmung bestimmbar, wobei sich die Federkraft ergibt aus der Rückstellkraft der einzelnen Federbügel und deren Anzahl.In addition to the friction surface that can be selected with regard to its dimensioning, the torsional inhibition can also be determined by determining the spring force, the spring force resulting from the restoring force of the individual spring clips and their number.
Der Federring, vorzugsweise aus einem Federstahl bestehend, kann aus einem einfachen, streifenförmigen Stanzteil hergestellt werden, das durch Biegen zu einem kreisrunden Ring mit geringem Aufwand zu formen ist. Dabei sind die beiden Enden vorzugsweise so (z.B. schlossartig) ausgebildet, dass sie zusammengesteckt formschlüs- sig ineinander greifen.The spring ring, preferably consisting of spring steel, can be produced from a simple, strip-shaped stamped part, which can be formed into a circular ring with little effort by bending. The two ends are preferably designed (e.g. lock-like) in such a way that they fit together in a form-fitting manner.
Eine Bearbeitung der Traverse ist ebenfalls nicht erforderlich, da der Federring außerhalb des Innengewindes der Traverse im Bereich der Sekundärdichtung, also auf der dem Druckstück zugewandten Seite, angeordnet ist und dort mit seinen Fe- derbügeln, die vorzugsweise als Federarme ausgebildet sind, an der Stellspindel reibend anliegt.Machining of the traverse is also not necessary, since the spring ring is arranged outside the internal thread of the traverse in the area of the secondary seal, that is to say on the side facing the pressure piece, and there with its spring clips, which are preferably designed as spring arms, on the adjusting spindle is rubbing.
In idealer Weise kann so der vorhandene Einbauraum zum Einsatz des Federringes genutzt werden, wobei als besonderer Vorteil hervorzuheben ist, dass der Federring auch in bestehende, also in Betrieb befindliche Scheibenbremsen, beispielsweise alsIn an ideal manner, the available installation space can be used for the use of the spring ring, whereby it should be emphasized as a particular advantage that the spring ring can also be used in existing disc brakes, ie in operation, for example as
Ersatzbeschaffung problemlos einbaubar ist. Hierbei können die vorhandenen Mon- tagewerkzeuge für die Nachrüstung oder einen Austausch eingesetzt werden. Die einfache Montage mit, der gleichermaßen problemlosen Anbindung an die Bremse führt ebenso zu einer Kostenminimierung wie die Herstellbarkeit unter Nutzung bekannter Technologien.Replacement procurement can be easily installed. The existing assembly daily tools can be used for retrofitting or replacement. The simple assembly with, the equally problem-free connection to the brake leads to cost minimization as well as the manufacturability using known technologies.
Der, wie erwähnt, vorzugsweise metallische Federring ist gegenüber einem solchen aus einem Kunststoff hoch temperaturbelastbar, so dass die auftretenden Betriebstemperaturen keine Auswirkungen auf die Standzeit dieses Bauteiles haben. Dazu trägt auch bei, dass ein solcher Federring mechanisch äußerst robust ist, d. h., den auftretenden Beanspruchungen gegenüber unempfindlich, wodurch eine hohe Lebensdauer erreicht wird. Dabei bietet es sich an, den Federring aus rostfreiem Federstahl zu fertigen.The, as mentioned, preferably metallic spring washer can withstand high temperatures compared to one made of plastic, so that the operating temperatures that occur have no effect on the service life of this component. This also helps that such a spring ring is mechanically extremely robust, i. i.e., insensitive to the stresses which occur, as a result of which a long service life is achieved. It makes sense to manufacture the spring ring from stainless spring steel.
Es ist auch denkbar, den Federring mit einer Dichtung integriert auszugestalten, Da- bei bietet es sich wiederum an, den Federring ganz oder teilweise zu umspritzen und/oder zu umschäumen. Die Federbügel werden dabei bevorzugt vom Umschäu- men ausgespart. Derart kann auf einfache Weise beispielsweise eine Sekundärdichtung z.B. in Ergänzung eines Faltenbalges als Primärdichtung hergestellt werden, welche das innere des Bremssattels gegen ein Eindringen von Feuchtigkeit schützt.It is also conceivable to design the spring ring integrated with a seal, in which case it is again appropriate to overmold and / or foam around the spring ring in whole or in part. The spring clips are preferably spared from foam. In this way, a secondary seal e.g. in addition to a bellows as a primary seal, which protects the inside of the brake caliper against the ingress of moisture.
Die Federarme können unterschiedlich geformt sein, beispielsweise in ihrem freien Endbereich U-förmig, wobei die offene Seite nach außen, also von der Stellspindel fort weist. Eine solche Formgebung bietet besondere Vorteile bei der Montage, d. h., beim Aufschieben des Federringes auf die Stellspindel (Nachmarkt), bzw. bei der Montage der Gewindespindel am Band, wenn sich der Federring bereits auf der Traverse befindet (Erstausrüstung).The spring arms can have different shapes, for example U-shaped in their free end region, the open side pointing outwards, ie away from the adjusting spindle. Such a shape offers particular advantages during assembly, i. that is, when pushing the spring ring onto the adjusting spindle (aftermarket), or when assembling the threaded spindle on the belt, if the spring ring is already on the crossbar (original equipment).
Die Breite der Federbügel, insbesondere im Bereich der Anlage an der Stellspindel, ist so bemessen, dass die Federbügel an mehreren Spitzen der Gewindegänge anlie- gen. Alternativ zu einem geschlitzten Ring, der sehr leicht zu fertigen ist, kann der Federring prinzipiell auch geschlossen ausgebildet werden.The width of the spring clips, in particular in the area of the system on the adjusting spindle, is dimensioned such that the spring clips rest on several tips of the threads. As an alternative to a slotted ring, which is very easy to manufacture, the spring ring can in principle also be made closed.

In der Figur 1 ist eine pneumatisch betätigbare Scheibenbremse dargestellt, die einen als Schiebesattel ausgebildeten Bremssattel 1 aufweist, der eine Bremsscheibe 3 in ihrem oberen Umfangsbereich umfasst.FIG. 1 shows a pneumatically actuatable disc brake which has a brake caliper 1 which is designed as a sliding caliper and which comprises a brake disc 3 in its upper circumferential region.
Prinzipiell ist auch eine elektromotorische Betätigung der Scheibenbremse möglich. Die Erfindung eignet sich ferner prinzipiell auch für Scheibenbremsen mit Fest- oder Schwenksätteln.In principle, an electromotive actuation of the disc brake is also possible. The invention is also suitable in principle for disc brakes with fixed or swivel calipers.
Beidseits der Bremsscheibe 3 sind Bremsbeläge 4 angeordnet. Zur Betätigung der Scheibenbremse mittels eines Zuspannens der Bremsbeläge dient dabei eine Zu- spannvorrichtung 2, deren genaue Funktion näher in der DE 94 22 342 beschrieben ist.Brake pads 4 are arranged on both sides of the brake disc 3. An application device 2, the exact function of which is described in more detail in DE 94 22 342, is used to actuate the disc brake by applying the brake pads.
Die Zuspannvorrichtung weist einen Drehhebel auf, welcher direkt oder über ein Zwischenelement wie ein Drehlager auf eine Traverse 16 einwirkt, welche mit Gewindebohrungen versehen ist, in welche Stellspindeln 10 eingeschraubt sind.The application device has a rotary lever, which acts directly or via an intermediate element, such as a rotary bearing, on a cross member 16, which is provided with threaded bores into which adjusting spindles 10 are screwed.
Zur Einstellung des durch Bremsungen vergrößerten Lüftspiels ist einer der Stellspindeln eine Nachstelleinrichtung 6 zugeordnet, mit der das infolge eines Belagverschleißes ändernde Lüftspiel durch Drehung der Stellspindel 10 nachgestellt wird. Die zweite Stellpindel 10 wird durch eine Synchronisationseinrichtung - hier eine Kette 7 - mitgenommen. Um zu verhindern, dass sich während des Fährbetriebs, beispielsweise durch Erschütterung, die Stellspindeln 10 unbeabsichtigt verdrehen und somit das Lüftspiel entsprechend in unerwünschter Weise verändert wird, ist jeder Stellspindel 10 ein Sicherungselement in Form eines Federringes 8 zugeordnet, das eine Mehrzahl von über den Umfang verteilte Federbügel 14 aufweist, die außerhalb des Innengewindes der Traverse 11 reibend an der Stellspindel 10 anliegen. Dies ist besonders deutlich in der Figur 2 erkennbar. Die Federbügel 14 sind axial an den Federring über Stege 21 angeformt bzw. mit diesen verbunden und stehen nach innen hin vom Federring 8 vor.In order to adjust the air play increased by braking, an adjusting device 6 is assigned to one of the adjusting spindles, with which the air play changing due to lining wear is adjusted by rotating the adjusting spindle 10. The second adjusting spindle 10 is taken along by a synchronization device - here a chain 7. In order to prevent the adjusting spindles 10 from unintentionally rotating during the ferry operation, for example due to vibration, and thus the air gap being changed in an undesirable manner accordingly, each adjusting spindle 10 is assigned a securing element in the form of a spring ring 8, which has a plurality of circumferentially Distributed spring clip 14 which abut the adjusting spindle 10 outside the internal thread of the crossmember 11. This can be seen particularly clearly in FIG. 2. The spring clips 14 are formed axially on the spring ring via webs 21 or connected to them and project inwards from the spring ring 8.
In diesem Beispiel ist der Federring 8 an eine elastische Sekundärdichtung 12 angeschlossen, die ebenso wie ein Faltenbalg 9, der mit dem Druckstück 5 verbunden ist, an einer Verschlußplatte 13 befestigt ist, mit welcher der Innenraum des Bremssattels 1 verschlossen ist. Weiter ist zu erkennen, dass der Federring 8 mit einem geschlos- senen Ringbereich 16 außenseitig an der Traverse 11 anliegt, während die Federbügel 14 in Form von Federarmen die Traverse 11 endseitig radial überragen und, wie erwähnt, an der Stellspindel 10 mit Anlageflächen 15 (Figur 4) anliegen.In this example, the spring ring 8 is connected to an elastic secondary seal 12 which, like a bellows 9, which is connected to the pressure piece 5, is fastened to a closure plate 13, with which the interior of the brake caliper 1 is closed. It can also be seen that the spring ring 8 with a closed ring area 16 lies on the outside against the cross member 11, while the spring clips 14 in the form of spring arms project radially beyond the cross member 11 at the end and, as mentioned, on the adjusting spindle 10 with contact surfaces 15 ( Figure 4).
Vorzugsweise sind fünf oder sechs Federbügel 14 gleichmäßig am Umfang des Ring- bereiches 16 verteilt.Five or six spring clips 14 are preferably distributed uniformly around the circumference of the ring region 16.
Jede Anlagefläche 15 wird durch den Rücken einer U-Form gebildet, deren dem Ringbereich 16 zugewandter Schenkel 24 einen Anschlag beim Aufschieben des Federringes 8 auf die Traverse bildet.Each contact surface 15 is formed by the back of a U-shape, whose leg 24 facing the ring region 16 forms a stop when the spring ring 8 is pushed onto the cross member.
Überdies können durch die genannten Schenkel 24 die Federbügel 14 unter deren Aufspreizung sehr leicht von beiden Enden her auf die Stellspindel 10 aufgleiten werden, wodurch sich eine einfache Montage und eine einfache Wartung ergeben.In addition, by means of the legs 24 mentioned, the spring brackets 14 can be easily slid onto the adjusting spindle 10 from both ends while spreading them open, which results in simple assembly and simple maintenance.
Wie die Figur 5 sehr deutlich zeigt, kann der Federring 8 aus einem streifenförmigen Stanzteil hergestellt werden, das an einem Ende eine Zunge 17 aufweist, während das andere Ende als Aufnahme 18 ausgebildet ist, in welche die Zunge 17 nach Verformung des Streifens zu dem Federring 8 korrespondierend eingreift, so dass ein Formschluß erreicht wird.As FIG. 5 shows very clearly, the spring ring 8 can be produced from a strip-shaped stamped part which has a tongue 17 at one end, while the the other end is designed as a receptacle 18, in which the tongue 17 engages correspondingly after the deformation of the strip to the spring ring 8, so that a positive connection is achieved.
Um ein montagebedingtes, unbeabsichtigtes Verbiegen der Federbügel 14 in axialer Richtung des Federringes zu verhindern, sind im Anschlußbereich jedes Federbügels 14 an den Ringbereich 16 axial sich erstreckende Nasen 19 vorgesehen, die den jeweils zugeordneten Federbügel 14 in seiner Höhe überragen, so dass diese Nase 19 praktisch einen Anschlag bildet.In order to prevent assembly-related, unintentional bending of the spring clip 14 in the axial direction of the spring ring, in the connection area of each spring clip 14 to the ring area 16 axially extending lugs 19 are provided, which project above the respectively assigned spring clip 14 in height, so that this nose 19 practically forms a stop.
Fig. 6 zeigt eine Variante, bei welcher der Federring 8 teilweise - bevorzugt bis auf die Federbügel 14 - umspritzt ausgebildet ist, so dass der Federring 8 mit einer Art Dichtringabschnitt 22 kombinierbar ist, was auf einfache Weise das Innere des Bremssattels gegen ein Eindringen von Feuchtigkeit schützt und insbesondere im Bereich des Nachrüstens bestehender Konstruktionen bei der Wartung sinnvoll ist.Fig. 6 shows a variant in which the spring ring 8 is partially molded - preferably except for the spring clip 14 - so that the spring ring 8 can be combined with a type of sealing ring section 22, which in a simple manner protects the inside of the brake caliper against the ingress of Protects moisture and is particularly useful in the area of retrofitting existing structures for maintenance.
Um zu verhindern, dass sich die als Schüttgut zu transportierenden Federringe 8 miteinander verhaken und so eine einfache Entnahme erschweren, sind bei dem in den Figuren 7 und 8 dargestellten Ausführungsbeispiel an die Nase 19 einerseits und an einen, und zwar den bezogen auf den Ringbereich 16 unteren, sich an die Anlagefläche anschließenden Schenkel 24 jeweils eine Anschlagschräge 24, 25 angeformt. Dabei ist die Anschlagschräge 25 der Nase 19 an einem sich nach innen erstreckenden, umgeformten Schenkel 23 vorgesehen und liegt in Gebrauchsstellung (Figur 8) an der zugeordneten anderen Anschlagschräge 26 an. Freie, hakenförmige Teile, die sich ineinander verkeilen könnten sind somit nicht vorhanden. BezugszeichenlisteIn order to prevent the spring washers 8, which are to be transported as bulk material, from getting caught and thus making easy removal difficult, in the exemplary embodiment shown in FIGS. 7 and 8, the nose 19 is on the one hand and on one, specifically in relation to the ring region 16 lower, adjoining the contact surface leg 24 each have a stop bevel 24, 25 formed. The stop bevel 25 of the nose 19 is provided on an inwardly extending, deformed leg 23 and is in the position of use (FIG. 8) on the associated other stop bevel 26. Free, hook-shaped parts that could wedge into each other are therefore not available. LIST OF REFERENCE NUMBERS
